I had a 1969 AT-1mx as did a several of my buddies. The one thing I remember quite well is that the material Yamaha used was very brittle and the pipes broke like crazy. The same for the perforated heat shield. If you are lucky to find one intact, I'm willing to bet it was pulled off the bike with less than 20 hours on it.

BTW, that pipe was also part of what was known as a "GYT kit" (get kit). The same pipe was used on the CT-1 (175cc).

Those pipes are a top dollar item,rare as hen's teeth these days. Most have been in the dumpster long ago.
I can still remember the sound they made sans muffler.

I remember the sound well, as i had a new one in 1971 and the sound was so sweet. We had to put silencers on them to race on all the MX tracks, $2.00 to ride or watch.http://i844.photobucket.com/albums/a...1/scan0002.jpg
